This is a loaded UK-centric policy/humanities term and I would suggest using sex/gender disparities instead which does not imply animus and is therefore much more useful for productive discussion.
Implicit and systemic biases in medicine are very real and supported by ample data.
> Systemic in particular is that basically the vast amount of knowledge amassed in the medical sciences has come from studying men. Comparatively little for those not assigned male at birth.
At least for the US this hasn’t been the case in clinical research for the past 15 years or so which in aggregate leans a bit more female than male if anything. Some specific fields still have sex disparity in clinical research for a variety of reasons but that’s the minority these days.
